Permit Fee Estimator Worksheet for New or Replacement Single Family Dwellings This worksheet is designed to help you estimate permit costs to build a new single family dwelling. Remember this is just an estimator and depending on your project, there could be other fees as well. Before you get started, you will need your building plans, plot plan, a scale (ruler) and a calculator. Please review the example plan and calculated fees in the middle of this package for reference. Step 1: Valuation of Construction Project To get started you will need to calculate the value of your construction project. This is done by determining the square footages of the different types of space in your project. Remember to measure from outside wall to outside wall. Living Space: includes bonus rooms, sun rooms, finished and semi-finished basements. Square feet of living space Square feet of garage/shop X $113.85 = (a) X $45.09 = (b) Square feet of covered porch/deck X $38.91 = (c) Square feet of uncovered deck greater than 30 above grade X $38.91 = (d) Square feet of unfinished basement X $21.00 = (e) (storage only, unheated, non-habitable space) Total valuation of project is a + b + c + d + e Step 2: Structural Permit Fees and Plan Review Fees $ Structural Permit Fees and Plan Review Fees can be found on the Building Permit Fee Calculator attached to this packet. To use the calculator find the total valuation from Step 1 in the first two columns of the Calculator under valuation. From the valuation columns you slide right to find your Permit Fees and Plan Review Fees. For example, if your total valuation is between $12,001 and $13,000 your plan review fees will be $190.45 and the permit fees will be $213.30. Plan Review Fee Permit Fees Total Structural Fees = a + b (a) (b) ((A)) Prepared by Benton County Community Development Department, Building Division Page 1 of 21 Revised 01/01/2017
Step 3: Departmental Reviews and Miscellaneous Fees Zoning (setbacks, wetlands, natural features, floodplain etc.) Public Works (driveways, access, water) Environmental Health (setbacks to septic etc) 79.00 (a) 51.00 (b) 76.00 (c) Addressing Fee (if new dwelling) 1 X $55.00 = (d) Road Approach 1 X $305.00 = (e) (This fee applies if access is from a county road or the current road approach does not meet current county standards if access is from a state highway, please consult ODOT) Total Departmental Reviews = a + b + c + d + e ((B)) Step 4: Plumbing Fees Plumbing Fees are based on the number of bathrooms plus 1 kitchen. This fee also includes: 1 st 100 feet of water/sewer lines, hose bibs, icemaker, under floor low point drains and rain drain packages. (Count a ½ bath as a whole bath.) Fees based on number of bathrooms: 1 bath/1 kitchen = $300.00 2 bath/1 kitchen = $400.00 3 bath/1 kitchen = $500.00 Fee for number of bathrooms (see above) Fee for each additional bathroom over 3 Qty: X $75.00 = (a) (b) Piping or private storm drainage systems exceeding the first 100 feet Each additional 100 lineal feet or portion thereof Qty: X $30.00 = (c) (Example: If the perimeter of your house is 320 feet, the first 100 feet is included in (a) and then you would have a remaining 220 feet which is 2 additional 100 feet and a fraction, therefore you would have 3 additional at $30.00.) Residential fire sprinklers (if required by RFD) 0 to 2,000 square feet $200.00 2,001 to 3,600 square feet $250.00 3,601 to 7,200 square feet $325.00 7,201 square feet and greater $410.00 Fee for fire sprinklers Plumbing Fees = a + b + c + d State Surcharge = Total plumbing fees X 12% (.12) Total Plumbing Fees = Plumbing fees plus surcharge (d) ((C)) Prepared by Benton County Community Development Department, Building Division Page 2 of 21 Revised 01/01/2017
Step 5: Mechanical Fees Mechanical Fees are calculated on each mechanical item with a minimum fee of $80.00. Fuel burning stove, fireplace, insert, lighter Qty: X $30.00 = Furnace, air conditioner, heat pump, air handler Qty: X $30.00 = Clothes dryer, exhaust fan, hood Qty: X $20.00 = Other appliance or equipment (Hydronic heating) Qty: X $20.00 = (a) (b) (c) (d) Gas piping system, new or altered (1 fee for all connections + equipment) Qty: X $20.00 = (e) Alteration to mechanical equipment or system Qty: X $20.00 = Mechanical Fees = a + b + c + d + e + f (Minimum fee $80.00) State Surcharge = Total mechanical fees X 12% (.12) Total Mechanical Fees = Mechanical fees plus surcharge Step 6: Electrical Fees (f) ((D)) Electrical Fees for Single Family Dwellings are based on the square feet of living space, unfinished basement and garage/shop. You do not need to include decks and porches. Square feet of living space: Square feet of garage/shop: + Square feet of unfinished basement: + Total square feet: First 1000 square feet Each additional 500 square feet or portion thereof = (amount used to calculate fees) 135.00 (a) Qty: X 25.00 = (b) (Example: If the total square feet is equal to 2225, you would have 1000 square feet at $135.00. This leaves 1225 square feet divided by 500, or 2.25 additional units. You would calculate 3 additional units at $25.00.) Limited/Restricted Energy Permit (Includes: alarms, garage door opener, vacuum systems, stereo, etc.) 1 X $25.00 (c) Electrical Fees = a + b + c State Surcharge = Total electrical fees X 12% (.12) Total Electrical Fees = Electrical fees plus surcharge (1) Prepared by Benton County Community Development Department, Building Division Page 3 of 21 Revised 01/01/2017
Additional Electrical Permits that may be needed Temporary Electrical Service Permit 1 X $72.80 (2) (Electrical service used during construction) Limited/Restricted Energy Permit (When not installed by contractor/owner wiring the house) Total of all Electrical Fees = 1 + 2 + 3 Step 7: Septic Permit Fees 1 X $72.80 (3) ((E)) If you are developing the lot for the first time, you will need a septic construction permit. This fee is based on the type of septic the lot was approved for. OR Type of Septic and the associated fee: 1-Standard, saprolite, steep slope: $1254 2-Sand filter, ATT, capping fill, tile dewatering & pressure distribution: $1809 Septic Construction Permit Fees (either fee 1 or fee 2) If this is a replacement dwelling, you will need a septic authorization permit. This is necessary to verify the existing system is in good working condition and capable of accommodating the proposed dwelling. Septic Authorization Permit Fees $812.00 Septic Fee (either construction permit or authorization) Step 8: Totaling Estimated Permit Fees Total Structural Fees ((A)) Total Department Reviews ((B)) Total Plumbing Fees ((C)) Total Mechanical Fees ((D)) Total Electrical Fees ((E)) Total Septic Fees ((F)) ((F)) Total Estimated Permit Fees = A + B + C + D + E + F Remember this is just an estimation of what you can expect permit fees to be. When you apply for permits, you will have a total of at least three permits. This would include a structural permit which includes items A, B, C, and D from above, an electrical permit, and a septic permit. You may also have a temporary pole electrical permit and limited/restricted energy electrical permit. If this is a replacement dwelling, you will have a demolition permit, which is a no fee item when applied for in conjunction with dwelling permit. If you have a low yield well, you may also need to get a water storage permit. Feel free to contact the Building Division or Planning Division with questions at 541-766-6819. Please note: If you live in either the Corvallis, Albany, or Monroe School District, you will be accessed a School District Construction Excise Tax equal to $1.00 per square foot for habitable space to be paid when your permit is issued to you. This fee is in addition to permit fees and is collected by the Building Division for the school districts.
